Okamoto Yasuyuki (1887-1946)

Okamoto commanded10 Divisionin Manchuria from January 1944. His
division was redeployed to Luzon in
late 1944, suffering very heavy losses en route. Placed under 41 Army control and ordered to
defend a line between San Jose
and Tayug, Okamoto believed his understrength division could not hold
the line assigned in such open country, and he chose to concentrate
elsewhere, but word of his decision was slow to reach Yamashita. This left the strategically important railhead at San Jose largely undefended. Okamoto's division was
virtually destroyed by the end of the war.
